Super Pico-second Whitening and Spot Removal Treatment

Light in laser treatments has a high-energy beam, and the parameters determining laser action include the pulse duration (the time it takes to emit the laser) and the wavelength of the laser. The wavelength represents different colors of light in nanometers (nm), and lasers with different wavelengths are absorbed by different substances. In the past, laser pulses used on the skin typically had a pulse duration of around 10-9 seconds (nanosecond), which is “one billionth of a second.” The latest laser technology, known as picosecond laser, has a pulse duration of approximately 10-12 seconds (picosecond), which is “one trillionth of a second.” This is significantly faster than traditional lasers, giving rise to the name “picosecond laser.”
